Aspect Ratios

I am currently reading through EADFAG and have hit a bump in the road concerning aspect ratios. I am working with the Ah! My Goddess! series which according to the box is 1.85 Anamorphic. When run through DGIndex it is identified as 16:9. When run through Premiere Pro (2.0) it comes up as "pixel aspect ratio from file" of square pixels 1.0 (I assume this means 1:1). When in the interpret footage window in Premiere I can "conform" the footage to several different aspect ratios. When conforming to anamorphic as the box says, the footage looks really squished. The best looking option, in my opinion, is the widescreen 16:9. I am confused as to how to handle the footage. Do I need to do any resizing? Should I use the conform option in Premiere or is there something better I can do with Avisynth?

Any and all help is appreciated.

How are you importing your footage? Did you convert the VOBs to Huffyuv or Lagarith AVIs or are you editing with the AVS (AviSynth) files directly?

I am editing with the AVS files directly.

Since DVD knows only two native formats - 4:3 and 16:9 anamorphic - the project setting for 16:9 widescreen will be right. 1.85:1 I find a bit weird for a series, because it's cinema widescreen, but if it really is, then it's letter boxed.

When viewed on a TV, it does have some minor letterboxing but looks nothing like it does when I change the aspect ratio to anamorphic in Premiere. Granted, my TV isn't widescreen either.

So should I keep it as is and just change the aspect ratio to 16:9 (1.2) as opposed to square pixel (1.0)? Is there anything avisynth-wise I should do? My AVS file only has commands for IVTS and assumefps(24) at the moment.

One way to handle it is to use AVISynth to resize to a square pixel aspect ratio before importing the footage into Premiere. In this case, since the footage was encoded anamorphic, you would want to

<b>LanczosResize(848,480)</b>
# if you don't like Lanczos, feel free to use the resize algorithm you prefer

(Of course, be sure to do this after IVTC.)
Then, the footage should look proper on your computer monitor: nothing getting stretched or squashed. It can now be imported into Premiere Pro and interpreted as all square pixels (1.0), so what you see is exactly what you get.

Of course, you'll have to make your Premiere Pro project resolution 848x480 to accomodate, unless you want to lose the sides of your footage when editing. This will require starting a new project (and importing the old one into it, if you had anything in the old project that you need).
